[Chimera-users] Chimera VTK file reader

Hi Andrew,

  I added a VTK file reader -- in tonight's Chimera daily build.  It handles vtk structured points files in ascii format like the one you gave me.  Your file had many -32768 values which seem to indicate regions where you don't have data and normal data values in a range 0 to 55.  This makes the histogram display of data values in Chimera worthless because the data range is 33000 but the meaningful range is 55.  Chimera is only able to show the whole range.  You might want to use some other value to indicate "no data", like -1 if negative values are not valid.

	Tom

This is one of the diffuse scatter maps that we discussed earlier: nearly identical to X-ray diffraction patterns except that the data values are applied to entire voxels as opposed to points. Any suggestions as to what I could try? Thank you so much!
